KNOXVILLE, Tennessee — What does the future hold for former Tennessee offensive lineman Antonio “Tiny” Richardson?

After his appearance at the NFL Combine, which officially wraps up on Tuesday, that answer is not entirely clearly.

Richardson was expected to be a late first round or early second round choice, according to many projections, but his combine performance was panned by some for being too slow.

That raises another question: His health.

Richardson underwent knee surgery after the 2012 season and at least one reporter — former Tennessee player Charles Davis — has suggested that his knee remains an issue. Davis even suggested that Richardson might have to “redshirt” his freshman season in the NFL.
